IMPROVEMENT IN STREET-LAMP POSTS.

Specification forming part of Letters Patent No. 208,326, datedSeptember 24, 1878; application filed February 9, 1878.

To all whom it may concern:

Be it known that I, JACOB G. MINER, of the city of New York, and countyand State of New York, have invented certain new and useful Improvementsin Street-Lamp Posts, of which the following is a full, clear, and exactdescription, reference being had to the accompanyin g drawings, andletters of reference marked thereon, in which- Figure 1 represents aperspective view of my improved lamp-post when erected. Fig. 2represents a sectional view of the separated sections of my improvedlamp-post; and Fig. 3 represents a top view of the horizontal collar, bymeans of which the sections of the lamp-post are connected with thesections of the gas-pipe.

Similar letters indicate like parts in all the figures.

My invention relates to improvements in street-lamp posts; and consists,first, in makin g such posts in sections coupled together byscrew-threaded gas-pipe couplings.

My invention further consists in the employment, in connection with thelamp-post sections, of sectional gaspipes arranged therein and connectedthereto, which pipes are connected by screw-couplings, thus uniting theseparate sections of the lamp-post together, as hereinafter more fullyset forth.

In the accompanying drawings, A A represent sections of a lamp-post,provided with swells or hollow protuberances at their lower ends, eachof which fits over the upper end of the section of the 1a1np-post nextbelow it, the sections of the lamp-post being united by a screw-threadedconnection, which I will now proceed to describe.

B B represent separate sections or portions of a gas-pipe, situatedwithin the hollow sections A A of the lamp-post, and connected theretoby a collar (represented in Fig. 3) attached to the sections A A,constituting the lamp-post, and to the sections B B, forming the gaspipewhen united together. This collar may be attached to the sections A A ofthe lamp-post and to the sections B B of the gaspipe by casting, or inany other well-known and convenient manner.

The lower end of each section A of the lamppost is provided with ahollow swell or protuberance, E, which fits snugly over the upper end ofthe section immediately below it.

The lower end of each separate section or portion B of the gas-pipe isprovided with a male screw, which is made to engage with the threads ofa female screw in the upper end of each section B of the gas-pipe.

By this construction the sections can readily be separated or unitedtogether, all soldering of the joints is obviated, and if one or moresections are injured, they can readily be replaced by others.

What I claim as new, and desire to secure by Letters Patent, is-- 1. Alamp-post made in sections coupled together by screw-threadedgas-pipeconnections, as herein specified.

2. The combination, with the sections A A of a lamp-post, of thesections B B of the gaspipe, arranged therein, and provided with thescrew-couplings O at their ends, as herein specified.

JACOB G. MINER.
